2 Background Palestine suffers from: • A non-secure electrical network • Palestinian Authority (PA) does not have any independence network in the West Bank • The electrical loads are increased, but the grid does not expand

3 Background • Palestine has a high solar radiation (Gr) and peak sunshine hours (PSH) amounts to about 3000 h and this is enough to produce solar energy in a sustainable way. • Availability of a large number of rural villages isolated from the electric grid. • High fuel cost in Palestine.

9 Scope (Expansion electrical network ) • It requires many as: conductors, insulators, towers, truss, transformer, switch gears, … etc. • It is more stable, but it is rarely existing on remote village

10 Studying Load (Froosh Beit Dajan) • located at east of Nablus 40 km • their population about 769 inhabitants in 100 houses • . It suffers from preventive, confiscation of lands and water • no electrical network despite of IEC pass through it. • The nearest point of medium voltage 33 KV return to PA far 6 km at Aien Sheply village.

15 The Sizing of the systems- PV: residential & tower • On tower we applied the min month Gr to keep the loads operating all times • Because the land of the tower is rented (not personal ) we add the size of land • a = area for 1 kwp=7. 055 m 2

18 The Sizing of the systems- hybrid: residential & tower • PV generator, storage battery, controller, inverter: is the same size of PV alone. • in tower we used average Gr because the DG get more stability of the system. • We used Ad= 1 day • Size of : DG rectifier

20 The Sizing of the systems- hybrid: water pumping • the diesel pumping used to compensate the percentage of Eh covered by PV. That means we cover 100% of Eh by two systems: PV and diesel, so we used two pumps for each. • e. g. : when the percentage of PV is 10% then the percentage of diesel is 90%

21 The Sizing of the systems-Expansion electrical network • When electrical network will be expanded, all loads in the village will be benefited from it.

31 Conclusion • The most economical alternative to electrify the village is extension electrical network, but we know that is prevented since 1967. • The most economical alternative to electrify the residential is the PV decentralized system at tilt 20 or 32 • The second economical alternative to electrify the residential is the hybrid system at tilt angle= 32, and it is more than reliable PV

32 Conclusion • The most economical alternative to electrify the tower is the hybrid with DC system at tilt 32, and it more than reliable PV • The second economical alternative to electrify the tower is the existing DG (it is more economical than PV) • The most economical alternative to electrify the pump is the diesel water pumping as existing now.
